Abstract

A pedal type bicycle transmission mechanism is characterized in that a transverse center long shaft is arranged in the center of a vertically-arranged fluted disc, a fixing plate is arranged on the right face of the fluted disc, a driving gear is arranged in the middle of the right face of the fixing plate, transmission gears are arranged on the front side and the rear side of the driving gear, and intermediate gears are arranged on the upper side of the front transmission gear and the lower side of the rear transmission gear and meshed with the driving gear and the transmission gears. The intermediate gear is connected with the fixing plate through a gear shaft, and the transmission gear is connected with the fixing plate through a synchronizing shaft; a synchronizing shaft penetrates through the fixing plate and the fluted disc, rolling gears are installed at the left end of the synchronizing shaft, a fixed gear is arranged between the two rolling gears and meshed with the rolling gears, a left fixed threaded pipe is arranged in the middle of the fixed gear, and the fixed gear and the fixed threaded pipe are arranged on the periphery of the central long shaft in a sleeving mode; the problem that a traditional pedal bicycle is strenuous is solved, and the pedal type bicycle is suitable for being assembled and used for various pedal type bicycles.

Description

technical field [0001] The invention relates to the field of human daily life means of transportation, in particular to a transmission mechanical structure of a pedal bicycle. Background technique [0002] Traditional pedal bicycles rely on manpower to alternately step on the pedals to make circular motions. Through the connecting rod between the pedals and the center of the toothed disc, the toothed disc is driven to rotate around the main shaft, and then the toothed disc passes through the chain, The flywheel drives the wheel to rotate, and its disadvantage is that due to the small gap between the length of the connecting rod and the radius of the chainring, it causes a large waste of manpower. Contents of the invention [0003] In order to solve the labor-intensive problem of traditional pedal bicycles, the present invention designs a transmission mechanism that uses gear conversion to save manpower. [0004] The technical solution of the present invention is a pedal-t...
